Figure 1. Schematic representation of the ocular movements when reading. In abscissa is FEM amplitude, in ordinate the fixation duration. The trend of the line represents the fixations/saccades alternation. The black circles refer to the landing sites, that in normal readers generally match the preferred viewing position. The dotted circles represent the skipped landing sites, since short words or high frequency words are generally processed parafoveally, therefore do not require fixation. Toward the end of the line a backward saccade (BS) takes place. At the end of the line a wide backward saccade (return sweep, RS) sets the fixation at the beginning of the next line
